Enabling
"System Parameters" menu, program parameter = P1 to P3 (see
5.2.2.1 Selection of the control circuit, pg. 56 and 5.2.3.2 Time
program, pg. 73).
Manual summer operation appears in the basic display with the
information SUMMER. If default programs P2 and P3 were
enabled, the corresponding symbol, Â, Ã or Ä, is also
displayed depending on the selected program. The symbols are
only displayed with the time program P1 to P3 active.
5.1.2.5.5 Continuous heating operation
The HEATING operating mode ensures continuous heating
operation without time limitations based on the specified daytime
room temperature. Hot-water production occurs continuously
based on the specified daytime hot-water temperature.
The HEATING operating mode remains active until another
operating mode is activated.
Activated continuous heating operation appears in the basic
display with the information HEATING.
5.1.2.5.6 Continuous lowering operation
The RED. HEATING operating mode causes continuously
reduced heating operation based on the specified lowered room
temperature. On the heating circuit levels, the reduced operating
mode ECO (frost-protected deactivation mode) or RED (lowering
mode) is set accordingly. The minimum temperature limit of the
respective heating circuit must be taken into account.
See the "Direct Circuit" or "Mixed Heating Circuit 1" / "Mixed
Heating Circuit 2" menu, reduced parameter = reduced operation
and 12 parameter = minimum temperature limit.
Hot-water production occurs continuously based on the specified
hot-water economy temperature (see "DHW" menu, hot water
parameter = hot water at night).
